摘　　要：对洪水灾害损失量能够及时、准确地评价,并提供给相关部门,对减少洪灾带来的影响具有重要意义。因此,为了更好更快地对洪水灾情进行统计,本文以一个乡镇作为洪灾模拟研究区,运用遥感的信息获取技术和GIS空间分析技术对洪灾损失快速有效地估算并以具体的经济货币量表征;建立了一个灾情的快速统计评估模型,准确快速地评估和分析灾情。该研究中的模型和评价方法可以推广到其他地区的自然灾害损失评估中。通过研究,本文提出了一个洪水灾情快速统计评估模型,下一步工作将该方法应用到实际发生洪水地区的灾情统计上面,为有关部门提供决策依据。Providing timely and accurate evaluation of flood disaster loss to relevant department has important significance for reducing the impact of the flood.This paper,uses a simulation of a township as a flood zone and access to information from remote sensing and GIS spatial analysis techniques to evaluate flood damage quickly and efficiently for characterizing the specific amount of money lost in the economy,and proposes a disaster rapid statistical evaluation model to quickly and accurately assess and analyze the disaster.Through the research,this paper puts forward a fast statistical evaluation model of flood disaster.Due to the limited information available,the next step of this research work will apply this method to the statistics of actual flood area and offer the decision basis for related departments.
